Some Common Errors

1. Unable to enumerate USB device under virtualbox.¶

1. Download the extension pack
   1. Open your file manager and double-click on the file that should be named something like Oracle_VM_VirtualBox_Extension_Pack-7.0.0.vbox-extpack. When you double-click that file, VirtualBox 7.0 will automatically open and install the extension pack for you.
2. Add user to vboxusers group
   1. For your user to do a number of things with VirtualBox, it must be a member of the vboxusers group.
   2. Open a Terminal window and issue the command:sudo usermod -aG vboxusers $USER
   3. Log out of the desktop and log back in.
3. Add specific USB device
   1. Open settings from the virtual box main screen.
   2. Settings > USB
   3. Select USB 3.0 from the menu.

2. SIOCSIFFLAGS: Operation not permitted and SIOCSIFHWADDR: Operation not permitted¶

This error happens when we want to disable a device like wlan0 (changing the MAC address). Simply use the sudo command to do that and it will work.

sudo ifconfig eth0 up/down
sudo ifconfig wlan0 up/down
